Minor cleanup & usability improvements.
1) Add format clarification to commands documentation.
2) Allow changing {canvas,brush} size w/ {<Ctrl> <Shift>,<Ctrl>} <Mouse wheel>.
3) Backend: {draw,produce,remove} cursor w/ list of coordinates instead of cells.
4) Update changing rendered cell size hotkey to <Ctrl> <Alt> <Mouse wheel>.

Release roadmap:
|
||||
1) {copy,cut,delete,insert from,paste}, edit asset in new canvas, import from {canvas,object}
|
||||
2) reimplement cursor unmasking w/ simple list of points
|
||||
3) operators: crop, scale, shift, slice
|
||||
4) auto{load,save} & {backup,restore}
|
||||
5) tools: unicode block elements
